----------------------------------
Yes. testPredEvalWithDateStats() has some invalid cases that should throw.
> Protection from exceptions in ORC predicate evaluation

> ORC evaluates predicate expressions to select row groups that satisfy
> predicate condition. There can be exceptions (mostly ClassCastException) when
> data types of predicate constant and min/max values are different.
> To avoid this patch catches any such exception and provides a default
> behaviour i.e; selecting the row group.
